本文为大家介绍一个H3C防火墙的配置实例，配置内容包括：配置接口IP地址、配置区域、配置NAT地址转换、配置访问策略等，组网拓扑及需求如下。
1、网络拓扑图
2、配置要求
1）防火墙的E0/2接口为TRUST区域，ip地址是：192.168.254.1/29；
2）防火墙的E1/2接口为UNTRUST区域，ip地址是：202.111.0.1/27；
3）内网服务器对外网做一对一的地址映射，192.168.254.2、192.168.254.3分别映射为202.111.0.2、202.111.0.3；
4）内网服务器访问外网不做限制，外网访问内网只放通公网地址211.101.5.49访问192.168.254.2的1433端口和192.168.254.3的80端口。
3、防火墙的配置脚本如下
